This role sits at the intersection of analytics, engineering, and business decisioning. You’ll help modernize how we build, deploy, and monitor credit models — ensuring our models not only perform well analytically but are also scalable, explainable, and production-ready.

Duties & Responsibilities - Strengthen Credit Risk Modeling and Credit Predictability

  • Build and enhance credit risk models that improve credit predictability and portfolio performance.
  • Conduct exploratory data analysis and experiment tracking to identify key risk drivers and optimize model outcomes.
  • Partner closely with Credit Strategy, Implementation, and Feature Platform teams to connect model insights directly to decision flows.
  • Keep our modeling framework adaptive to changing credit dynamics and economic conditions.
  • Duties & Responsibilities - Bridge Data Science and MLOps for Reliable Model Delivery

  • Own Python project structure, CI/CD setup, and end-to-end testing for reliable model delivery.
  • Collaborate with MLOps and Feature Platform teams to maintain model pipelines (e.g., Metaflow, SageMaker, or equivalent orchestration frameworks).
  • Support model deployment, validation, and performance consistency in production.
  • Drive standardization, automation, and reproducibility across the modeling lifecycle.
  • Duties & Responsibilities - Support Model Monitoring and Governance

  • Expand and maintain monitoring frameworks for production models.
  • Support compliance reviews, validation exercises, and performance monitoring (e.g., PSI/CSI analysis, reject inference).
  • Maintain audit-ready documentation and ensure transparency across model development and production processes.
  • Requirements

  • Bachelor’s degree in a quantitative field (Statistics, Mathematics, Computer Science, Engineering, Data Science, or related).
  • Master’s or PhD preferred.
  • Strong understanding of the model lifecycle (EDA, modeling, evaluation, deployment).
  • Proficiency in Python (pandas, scikit-learn, etc.) and SQL.
  • Experience with Metaflow or similar orchestration frameworks (e.g., Flyte, ZenML, SageMaker Pipelines).
  • Familiarity with cloud environments (AWS preferred).
  • Experience with model deployment (FastAPI + Docker or similar).
  • Understanding of version control (Git/GitHub), unit testing (pytest), and modern Python tooling (e.g., uv, poetry).
  • Proven accountability, communication, and work ethic — able to deliver high-quality work on time with minimal oversight.
  • Nice to Have

  • Background in credit risk modeling or lending-related ML applications (e.g., underwriting, loss prediction, fraud detection).
  • Experience integrating ML solutions with decision systems or APIs.
  • Familiarity with model monitoring frameworks or model governance processes.
  • Comfort working in cross-functional teams and presenting technical results to non-technical stakeholders.
